TomTom HD Map

Our market-leading high-definition map improves sensor perception, enables precise localization and improves path planning to safely execute every maneuver.

Precision HD mapping for safe autonomous driving

As we move towards an autonomous future, industry analysts agree that HD maps are essential to making safe autonomous driving (AD) possible. With driving gradually shifting from humans to machines, the role and scope of digital maps must go beyond navigation and be built specifically for self-driving vehicles. The TomTom HD Map is the next generation, delivering highly accurate, up-to-date and realistic representations of the road.
Market-leading technology for self-driving vehicles
Since its launch in 2015, the TomTom HD Map has been integrated into successful R&D projects with 4 of the top 5 global OEMs. We are the market leader, with our map in autonomous vehicles produced by top automakers around the world*. We are also the first HD map supplier to achieve broad highway coverage of the U.S., Europe and east Asia.

* Based on 2018 car production volumes, excluding China (source: IHS).
Vehicle positioning

Vehicle positioning

A self-driving car needs to know where it is at all times. The TomTom HD Map helps vehicles know their exact location on the road – down to the centimeter.
Autonomous driving perception

360-degree perception

Is it a tail light, traffic light or street light? In complex environments, the TomTom HD Map helps locate and identify signs, lights, poles and other objects to help self-driving vehicles make sense of their surroundings.
Autonomous driving path planning

Path planning

Changing lanes, taking exits and other on-the-road maneuvers are complex for self-driving vehicles. The TomTom HD Map helps vehicles plan a path along any route and execute it safely.
Autonomous driving sensors

Extended sensor range

The TomTom HD Map works together with onboard sensors to validate and prioritize the info they provide. Our map gives context to the vehicle’s surroundings, acting as a safety net that sees road signs, lights and around corners.
Autonomous vehicle localization

Sensor-agnostic localization

TomTom RoadDNA works with any sensor layout to enhance positioning with localization map layers that contain multiple sets of format-friendly data. This accurate, robust localization retains position awareness, especially in poor weather.

How do we efficiently deliver the latest TomTom HD Map? TomTom AutoStream.

To ensure the automated driving system reflects accurate road information, we developed the TomTom AutoStream delivery system, which efficiently provides the most recent and relevant HD Map data. This also comes with onboard client software, including ADASIS v3 horizon provider, making TomTom AutoStream a complete, ready-for-integration solution.
HD Map
We minimize change detection and upload time to quickly process updates. Our map-making engine, CPP, releases new Roadagram updates to AutoStream to deliver the latest map data in variable tiles.
Thanks to 30 years of experience, our lead in functional safety, OEMs have made us the market-share leader.
Our HD Map contains lane geometry and classification, sensor-agnostic RoadDNA and an attributed road network model. HD road-classified objects include relevant lane objects, point features and road areas.
